Give your “Belief Engine” a tune-up

Salon interviews Lewis Wolpert about his new book called “Six Impossible Things Before Breakfast“. Wolpert believes that our understanding of cause and effect not only drove our ability to make tools but also contributed to the development of what he terms the “belief engine” in the brain.

I’m going to paraphrase the interview but I don’t think I’m off here when I say that Lewis Wolpert believes that our brains are hard-wired for causal beliefs and more soft-wired for religious or mystical beliefs and that evolution selected those with religious beliefs because believers are less anxious and more optimistic. I’ve seen this argument made before although I can’t find any reference to site here. Anyway, most of the benefits ever given I think would contribute to living longer or better surviving illnesses that quite frankly strike the older generations. Evolution selects through reproduction right? Most older generations are not continuing to have children, it is the younger generations. So what kind of meaningful selection can evolution have when the advantage in this case is one of primarily longevity, not fertility?

Perhaps natural selection should be made here in reference not to the individual but to the society in general. Religion provided more stable societies which indirectly led to a more consistent food supply, social cohesiveness and indirectly reproduction within these particular societies. Of course, members of these societies would carry on and expand on this religion over time so that it would better suit their growing societies. To me this sounds more like an anthropological or sociological argument than one of evolution or natural selection.

I know I have digressed from the point of the interview and ultimately the book itself, which is that our brains have developed to find cause and effect and have therefore invented gods and other invisible agents (I think Steven Pinker’s book Blank Slate talks about invisible agents and our propensity for belief) to explain the unexplainable.

Dembski vs. Shermer

Just doing some YouTube trolling and came across this little gem. It’s William Dembski and Michael Shermer talking about Intelligent Design on CNN. It’s only 5 minutes or so but still worth a watch. Notice how Dembski likes to throw a bunch of things out there and then the moderator has to interrupt so that we can even hear Shermer’s response. But then again I’m biased.

Oh, please let it be Adam and Eve!!!

Recent genetic research on the mitochondrial DNA of Australian Aboriginees and Melanesians from New Guinea show that they all come from a common ancestor group and further confirms the all of humanity shares the same ancestry. 

Maybe we’ve got the location of the Garden of Eden wrong. I’ll have to go back to my Bible to figure out where I went wrong. Oh wait, I figured out the problem, it’s because I’m using the Bible to guess at scientific truths.

100% Organic and Naturally-selected.

Make sure you have time to read this one, What makes natural selection a process powerful enough to bring about the evolution of adaptations?, but it covers the topic quite thoroughly without gettting too sciency, I think I made up my second word this week.

Stuck between a rock and a … coal mine

News story on NewScientist, Huge fossilised rainforest found in coal mine. I have one problem and one concern about this article. The problem I have is that the article credits “researchers” as having discovered this rainforest on the ceiling of a coal mine. Seems to me that maybe a miner is the one who found it since paleobiologists aren’t in the habit of strolling around coal mines, maybe I’m wrong.

The concern I have is the inevitable “proof of The Flood” story this sentence will generate:

…when a large earthquake or other catastrophic event caused the entire region to suddenly drop below sea level.

Fodor vs. Dennett

Interesting kerfuffle between Jerry Fodor and Daniel Dennett over Fodor’s paper disputing the existence or validity of evolutionary psychology. Check out the ScienceBlogs post with comments and links to the original papers.

Miller-Urey, v.2.0

While the original Miller-Urey experiments have been shown to not contain a representative early Earth atmosphere, new experiments by the Scripps Institution of Oceanography in La Jolla, California show that with the introduction of iron and other carbonate materials that a more representative early Earth atmosphere and a spark of lightning could indeed create an explosion of amino acids that closely represent the results of the original experiment.
